Jonathan Roberts, cartographer for Kobold Quarterly and Adventures in the Hyborian Age, presents another Fantastic Map: Arena of Fire.

This multi-page PDF allows you to print out two different battlemaps (above- and below-ground) at a 1 square=1 inch scale letter-format map; you can also choose printer-friendly light grayscale versions. You also get two high-resolution JPEGs of the maps with and without grids, along with individual images for the runic circles. The file also contains two Maptool campaign files set up for quick use with the 4th Edition of the world's most popular roleplaying game and its 3.5 thriving spiritual successor. (The Maptool file requires Maptool 1.3b60 or newer.)
